Motors, of which the following is a speci'lication.

My invention relates to hydraulic motors f of the class adapted for Washing machines, or for other purposes and this is a. division 01' my splice-tier serially munbered 333,937 and fl ed September '10, 1906.

The objects of my improvement are to provide the balanced valves with means for actuating them instantly and for locking them in both the ooen and the closed posi tions; to provide adjustabl means for con trolling the length of the stroke of the piston, and to provide a. sim lo and durable cons-truction combined. witn facility of operation and efficiency of action. These ob ects are attained in the following described manner, as illustrated in the eccom mnying drawings, in which Figure 1 is a, side elevation with in section on the line a-a cf Fig. 2 of hydraulic motor embodying my improvements Fig. 2, a rear elevation; Fig. 3 a plan with parts broken away and parts in section on the line b of Fig. 1; Fig. l. a horizontal section of the valve chambers with the v lves in o )crative positions therein; Figs. 5

and 6 detei s of the valve actuating mocha? ism.

In the drawings, the cylinder 1 is mounted on a bed plate 2 and provided with piston-3, piston rod 4 end with recessed lugs 5 in its heads. Uylindrical valve chambers 5 and. 7 are each connected with the corresponding lugs 5 at each end of the cylinder by means of branch 1i )es Said lines are orovided with. lateral openings. 9 Within, and are secured to said by means of screw cups 1 1. Chamber 6 is provided with e discharge pipe 12 and with a valve stem 13 whereby valves 14: are movable to open or close the ports 15 therein. Chamber 7 is provided with ports 16 and. w. h a supply };ip'e l7 adapted to communicate through 2t lose with u hydra-tut -0 or other source of water under pressure. Said chamber is also provided with s. lve stem 18 whereby valves 19 thereon are movable to open or close the-ports 16.

The valve stems are adjustebly connected together by means of transverse bars 21 and they are movable in stationary guides 2P3. A vertical hollow column 23 is formed. on the bed plate and a rocker arr 2 1 trunnioned thereon in e-vcrtical plene' with the piston rod. Said arm is provided at its ends with a1:1tifriction rollers 25 and with :1 Wing which depends from its middle portion and.

l is formed with its edges converged to a point 27. Tepering tap pets 28 zuljustebly secured.

on the iston rod are alternately carried thereby into contactwith the corresponding rollers 25 for oscillating arm. 24, whereby the Wing 26 alternately contacts with the corresponding bars 21 for actuating the valve rods with the valves thereon sinmltaneously in either of opposite directions.

A latch 31 with its edgestepered to a point is movable within column and actuated by means of a spring- 32 with either of its edges into engagement with the correspond ing edge of Wing 25 for yieldingly maintaining the rocker arm in either extreme position of its oscillation. The exert-ion of said spring also causes the latch to instantly complete the oscillation of the rocker arm in either direction. after the point of the Wing has been. moved beyond the point of the latch by the action oft-he tappets.

in operation, when the valves are in the position shown in Fig. 4 the piston will be moved in a. forward direction indicated by the arrow in Fig. i. The con tact of the front tap at with the rocker arm moves the point of the wing heyond the point or the lat-(331 end in contact with the rear crossbar Spring 32 than forces the latch to complete the rear ward movement of the wing for completing the oscillation of the rocker arm and for si znulleneously shifting the valve rods v m the valves in reversed positions for movmg the piston in the reserve-rd direction. The valves are locked and maintained in either position under a yielding pressure by the rt'ion of the spring on the latch. The rm. pets may be adjusted along the piston ml.- desired to control the length of its stroke ll aving' dos-"'ribed my invention what I claim i.
